WALL STRUCTURE.

Application filed July 25, 1918.

To all whom it may concern:

Be it known that I, Gnoncn I YoUMANs, a citizen of the United States, residing at Galesburg, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Vail Structures, of which the following is a specification.

This invention relates to improvements in wall structures.

The main objects of this invention are:

First, to provide an improved circular wall structure having considerable height such as a silo, built of relatively short wood staves and one which is very rigid, strong and durable.

Second, to provide an improved wall structure formed of wood staves, in which the joints of the structure are effectively protected from exterior moisture.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Figure I is a front elevation of a silo em bodying the features of my invention.

Fig. II is an enlarged detail with the hoops omitted showing details of the arrangement of the staves.

Fig. III is a similar detail showing the manner of starting the wall.

Fig. IV is a detail vertical section on a line corresponding to line 44 of Fig. II showing details, of the hoop channels.

Fig. V is a detail vertical section on a line corresponding to line 55 of Fig. II, showing one of the intermediate hoop channels.

Fig. VI is a detail section similar to that of Fig. IV showing a slightv modification.

In the drawing, similar reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Specification of Letters Patent.

Patented Apr. 6, 1920.

Serial No. 246,673.

Referring to the drawing 1 represents the base of a silo, 2 the roof and 3 a series of doors. These parts are shown conventionally. The staves 4 are preferably five or six feet in length although this may be considerably varied as desired. The staves in the structure illustrated are arranged in half lapping courses with their ends abutting and in starting and finishing the wall I employ half-length staves 5. When the staves are disposed in half lapping courses each stave is provided at the center with a transverse hoop channel 6 which is preferably deepest at its edges, providing a central bead 7. Each stave has a rabbet-like recess 8 at each end which coact with the recesses of abutting staves. to provide hoop channels alined with the channels 6, thus forming continuous channels around the wall for the hoops 9. These hoops are preferably channel-shaped in cross section as shown in Figs. IV and V, and are disposed to embrace the beads 7.

The upper edges 10 of the channels are preferably undercut providing drip ledges 11, while the lower edges 12 of the channels are outwardly inclined so that the water runs or drains freely therefrom. The hoops being channel-shaped bind or engage only at their edges so that very perfect oints are formed between the hoops and the bottoms of the channel.

In the modification shown in Fig. VI the,

hoop 13 is rectangular in form, the bead being also rectangular.

Vith this arrangement of parts I provide a joint which effectively excludes the moisture and at the same time am enabled to use short wood staves in erecting circular wall structures, which when erected are very St oIw and rigid and durable and are economical to construct. The channels are preferably of such depth that the hoops lie entirely within the channels but the structure is very satisfactory if this feature is not present.

I have illustrated and described my improvements in the embodiment preferred by me. I am aware that very considerable variation is possible and satisfactory results still be secured. I have not attempted to illus trate or describe such variations as I believe the disclosure made will enable those skilled inthe art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A cylindrical wall structure comprising staves laid in half lapping courses with their ends abutting and having transverse central hoop channels and rabbet-like end recesses coacting to form hoop channels alined with said central channels, the channels being deepest at their edges providing 7 heads within the channels, the upper edges of the channels being under cut providing drip ledges, the lower edges of the channels being outwardly inclined, and channelshaped hoops disposed in said channels to embrace said beads, the depth of the channels being such that the hoops lie within the plane of the surface of the wall.

2. A cylindrical wall structure comprising staves laid in half lapping courses with their ends abutting and having transverse central hoop channels and rabbet-like end recesses coacting to form hoop channels alined with said central channels, the channels being deepest at their edges providing beads within the channels, and channelshaped hoops disposed in said channels to embrace said beads, the depth of the channels being such that the hoops lie within the plane of the surface'of the wall.

3. A cylindrical wall structure comprising staves laid in half lapping courses with their ends abutting and having transverse central hoop channels and rabbet-like end recesses coacting to form hoop channels alined with said central channels, the upper edges. of the channels being under-cut providing drip ledges, the lower edges of the channels being outwardly inclined and hoops disposed in said channels, the depth of the channels being such that the hoops lie within the plane of the surface of the wall.

4. A cylindrical wall structure comprising staves laid in half lapping courses with their ends abutting and having transverse central hoop channels and rabbet-like end recesses coacting to form hoop channels alined with said central channels and hoops disposed in said channels, the depth of the channels being such that the hoops lie within the plane of the surface of the wall.

5. A cylindrical wall structure comprising staves laid in interlapping courses and having intermediate channel grooves alined with the joints of abutting staves and rabbet-like endrecesses coacting to form hoop channels alined with said intermediate channels of adjacent staves, the channels being deepest at their edges providing beads within the channels, and channel shaped hoops disposed in said channels to embrace said beads therein.

6. A cylindrical wall structure comprising staves laid in interlapping courses and having intermediate channel grooves alined with the joints of abutting staves and rabbet-like end recesses coacting to form hoop channels alined with said intermediate channels of adjacent staves, and hoops disposed in said channels.

7. A cylindrical wall structure comprising staves laid with their ends abutting and having end recesses coacting to form hoop channels having a bead at the joint, the upper edges of the channels being under-cut providing drip ledges, their lower edges being outwardly inclined, and channel shaped hoops disposed in said channels to embrace said beads therein,the depth of the channels being such that the loops lie within the plane of the surface of the wall.

8. A cylindrical wall structure comprising staves laid with their ends abutting and having end recesses coacting to form hoop channels having a bead at the joint, and channelshaped hoops disposed in said channels to embrace said beads therein, the depth of the channels being such that the hoops lie within the plane of the surface of the wall.

, 9. A cylindrical wall structure comprising staves laid with their ends abutting and having end recessescoacting to form hoop channels, the upper edges of the channels being under-cut providing drip ledges, their lower edges being outwardly inclined, and hoops disposed in said channels.

10. A cylindrical wall structure comprising staves laid with their ends abutting and having end recesses coacting to form hoop channels, the upper edges of the channels being under-cut providing drip ledges, and hoops disposed in said channels.

11. A cylindrical wall structure comprising staves laid with their ends abutting and having end recesses opening into each other and coacting to form hoop channels, and hoops disposed in said channels the depth of the channels being such that the hoops lie within the plane of the surface of the wall.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
